R\-Pi\-G\-P\-I\-O\-Pin Here we define Raspberry Pin G\-P\-I\-O pins on P1 in terms of the underlying B\-C\-M G\-P\-I\-O pin numbers. These can be passed as a pin number to any function requiring a pin. Not all pins on the R\-Pi 26 bin I\-D\-E plug are connected to G\-P\-I\-O pins and some can adopt an alternate function. At bootup, pins 8 and 10 are set to U\-A\-R\-T0\-\_\-\-T\-X\-D, U\-A\-R\-T0\-\_\-\-R\-X\-D (ie the alt0 function) respectively When S\-P\-I0 is in use (ie after \hyperlink{group__spi_gac888dc9b78b695f6c13eeeaa813c0d82}{bcm2835\-\_\-spi\-\_\-begin()}), pins 19, 21, 23, 24, 26 are dedicated to S\-P\-I and cant be controlled independently.
